The DBA 4000 Series cross-drilled front rotor with silver hat for 2015–2020 Volkswagen Golf R is cast from XG-150 high carbon alloyed iron and undergoes Thermal Stability Profiling. Combined with Kangaroo Paw ventilation, the design increases surface area and cooling efficiency over straight vane rotors, while the XD non-directional cross-drilled and dimpled face provides added cooling and a sporty appearance.
